You don't, the EIS-4000 does not accept shunts. The
EIS-4000 can use 0 to 5 volt input to the aux inputs. Any
attempt at directly connecting the shunt to the EIS-4000
will likely cause permanent damage to the instrument.
With that said as I mentioned on VAF forum you need a
hall effect. If you want multiple current measurements you
need an additional hall effect current sensor. The hall effect
is connected to one of the AUX inputs. I can help you setting
the EIS-4000 up when you get your hall effect. You will need
to set the scale factor and off-set. If you purchase a hall
effect from GRT they provide instructions. If you have a Q email me.

I am building an RV7 electrical system according to the Z-12
architecture and want to make the fusible link from the aux
alternator to the starter contactor depicted in the diagram. Bob's
online article about fabricating a fusible link and the B&C kit say
that it only applies to 22 and 24AWG fusible links, whereas the Z-12
diagrams lists a 16AWG fusible link. Can't find a resource that
explains how to do this. Help?
Thanks all

I followed the trail to the site of the penetration kits at EPM wherein the
sealant is referred to as "Biotherm 100 silicone fireblock sealant."
Since I wanted to use a similar material for other penetrations, I attempted
to further search the net for the subject sealant. there is no source other
than EPM, so am not sure of its specifications.
Any clues out there?

This putty is used in a VERY thin interface between firewall
and the flange of the fitting. Any fire-retarding material
(from plumbing and/or electrical supplies section of well
stocked hardware store) will do.

Most of the time, no . . .
However, most operating systems have an embedded list of
file extensions intended to tell the system what application
is used to open which type of file. In this case, the file
is a .pdf extension and is opened with one of Adobe's several
viewing/editing applications for .pdf files.
The problem arises when the combination of applications running
in your system get the cart in front of the horse (a hazard
of systems designed for multitasking). I believe folks are getting
the error message you've noted because Acrobat is being prompted
to open the file while it's still being downloaded . . . hence,
Acrobat sees a truncated file and assumes that it's damaged.
The 100% sure method for downloading large data files of
any type from any site is to right-click the link and tell
your browser where to STORE the file on your hard-drive.
Wait until the download is complete and THEN open the
file with the appropriate application.

I have some of their kits but have not installed them yet. So I went out to
look at the tubes of sealant. Unfortunately they are blank white tubes. In
searching with Google I found this in the Aeroelectric archives in a message
from David Carter on Dec 4th, 2003:
"Wonderful product (epm.av's) that mimicks Bob's home grown grab bar
solution
and adds the 2000 degree "Biotherm 100 silicone fireblock sealant" to dress
the end of "fire sleeve stuffed sleeve of fire sleeve".
I just called and they buy the VERY expensive sealant and repackage into 1.5
oz doses to sell with the kits."
Me, I would just use RTV - I have turned a blowtorch on it for minutes and
seen no effect.

--> AeroElectric-List message posted by: "Craig Payne" <craig@craigandjean.com>
I wondered about this so off I went to the GRT site. At:
www.grtavionics.com/model_4000&6000.htm
I found:
"Functions :

* 6 Auxiliary Inputs user configurable can provide:
...
* Ampmeter" <<<<<<<<<<<<<<
To monitor the voltage drop across a shunt you need a differential
(double-ended) input to the analog/digital converter. Since the manuals for
the EIS 4000 are not on-line I don't know if it has any.
I'm using a Honeywell CSLA1CE Hall effect sensor. I believe both Blue
Mountain Avionics and Advanced Flight Systems use a part from the same
family.

That's the best solution: send $60 to GRT and get their current sensor,
which also comes with some instructions. Then just change your diagram
from showing shunts to showing the current-carrying wire passing through
the GRT "loop" current sensor. In some ways, it's easier to install
than a shunt . . .

Home depot in the caulk section. Specifically it is 3M Fire Barrier =
Sealant CP25WB. Anything that is rated for through penetration void =
sealing in construction should be fine but the Intumescent is generally =
considered the best.
Hope this helps.

Sorry I don't read French and too lazy to use Babelfish. But I do
enjoy looking at pictures and if I am understanding your pic's correctly it
looks as though you are using industrial type electrical connectors for the
penetration and just sealing with high temp 3m and a fire sleeve. Which I
don't see why it would not work. Even if the connectors are just galvanized
steel and not stainless.

Randy,
My web page is divided into 4 parts :
- Roles of the firewall
- What's NOT to be done (IMHO) : rubber grommet, putty patch...
- What I did : home made STAINLESS steel penetrations
- What others do : brass fittings, Bob's method, grommet shields, EPM.AV
Corp' fittings
You may really wish to use Google translator, after all ;-))
